checkpatch: kconfig: prefer 'help' over '---help---'
IMO, we should discourage '---help---' for new help texts, even in cases where it would be consistent with other help texts in the file. This will help if we ever want to get rid of '---help---' in the future. Also simplify the code to only check for exactly '---help---'. Since commit c2264564df3d ("kconfig: warn of unhandled characters in Kconfig commands"), '---help---' is a proper keyword and can only appear in that form. Prior to that commit, '---help---' working was more of a syntactic quirk. Signed-off-by: Ulf Magnusson <ulfalizer@gmail.com> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
